Depending on the TDS content of the water in your area, this may recur if the water is allowed to dry by itself on the vehicle , especially if warm or sunny.

Solutions to counter this in the future are;
1) drying with a clean towel as soon as a section is washed and cleaned.
2) spray -on waxes
3) DI water (can get expensive), especially if TDS levels are quite high.

Edit; this can happen regardless of coating.
